Sometimes they get in through an open door or window. Others may come down the chimney and through the fireplace. However they got there, a squirrel who has entered a house is there by accident and will be desperate to get out.
Show that squirrel the door
Place your pets in another room. Close all interior doors and open a window or exterior door in the room. Leave the squirrel alone, so they can find their way out. They may even jump from a second-story window onto a lawn without harming themselves, but don’t let them jump onto concrete.
If there is no possible exit, set a humane trap baited with peanut butter on the floor near the squirrel and leave them alone for a few hours. If obtaining a live trap isn’t an option, try this method using a blanket:
- Put on heavy gloves.
- Slowly approach the squirrel with the blanket held in front of your body, so that they don’t see a human form.
- Drop the blanket on the squirrel and quickly roll it up, taking care not to put too much weight or pressure on them.
- Take the squirrel in the blanket immediately outside and gently open the blanket on the ground, letting the squirrel escape.
Once the squirrel is out, look for the entryway and take steps to keep it from happening again. Look for tracks in soot or dust around the fireplace or furnace that may show the animal came down the chimney or flue and check the attic for evidence of a nest or entrance hole that may need repair.
Relocating doesn’t work
Live-trapping squirrels and taking them to "the woods," where they will live happily ever after, is not the ideal solution to local problems. Studies show that few squirrels may survive the move. And when a squirrel is removed from a yard, another squirrel will move in, sometimes within a few days.
